black and white portrait
Heteronema (het-err-owe-knee-ma) splendens Larsen and Patterson, 1990. Cells are elongate-cylindrical, about 140 microns long, and metabolic with pellicular striations following an S-helix. An ingestion organelle is visible near the flagellar pocket and is slightly developed with two rods, but it can be overlooked when the cell is squirming or gliding. Two flagella are of unequal length, the anterior flagellum is about the cell length, and the posterior flagellum is about half the cell length and does not attach to the body. The large nucleus (20 x 9 microns) normally lies near the centre of the cell. The cells were full of disk-shaped small granules. The cells move by squirming or gliding. Rarely observed. This picture was taken by Won Je Lee using conventional photographic film using a Zeiss Axiophot microscope of material collected in marine sediments of Botany Bay (Sydney, Australia). The image description refers to material from Botany Bay. Image copyright: Won Je Lee, image used under license to MBL (micro*scope).
